I tried to download the drivers for the no name scanner (Mustek d6ep61321.exe) but scanner did not work. During installation everytime I tried to install the a-drive, it went to the c-drive. I read that a lot of other people dealt with the same problem.
Now I think I found a solution via internet.
So my scanner is installed now.
The solution is also a driver from Mustek but it is another type.
